Torsion of ovary, ovarian pedicle, or fallopian tube

This code signifies the twisting of an ovary, its supporting pedicle (the vascular and ligamentous stalk), or a fallopian tube. This twisting compromises blood supply, leading to ischemia and potential necrosis of the affected adnexal structures. It is an acute gynecological emergency.

Assign this code when documentation clearly indicates a diagnosis of ovarian torsion, fallopian tube torsion, or torsion of the adnexa. This typically presents with sudden, severe unilateral pelvic pain, often accompanied by nausea and vomiting. Imaging studies, such as ultrasound with Doppler, frequently support the diagnosis by showing an enlarged, edematous ovary and/or absent blood flow.

• Differentiate from other causes of acute pelvic pain, such as ectopic pregnancy or appendicitis, which have distinct codes.
• Ensure documentation specifies "torsion" and not just "adnexal mass" or "ovarian cyst," as these are not sufficient for this code.
• This code is often a primary diagnosis for surgical intervention (e.g., detorsion, oophorectomy).
